Replacing wall outlets and Pigtailing properly will help as you’ll eliminate the chance that any older outlets with steel screws or with bad connections are still in use.

I see a lot of narrative around, "cut your costs, eliminate unnecessary expenses" etc.

The main "goal" of house hacking is subsidizing or completely eliminating your housing expense through renting out other portions of your home. 

This exemption can substantially reduce or even eliminate your capital gains tax obligation, depending on the profit you realize from the sale.

I will be amending my contract to eliminate any issues with this in the future.

@Alex Bell, I would keep in mind, rents will most likely go up, so will home values, you will be able to take advantage of many tax benefits.

The trust's tax status and provisions can significantly impact the calculation of capital gains tax.Moreover, there are various exemptions and strategies that can potentially reduce or eliminate capital gains tax, such as the primary residence exclusion for individual sellers, which isn't automatically applicable to trusts but may still benefit the beneficiaries under certain conditions.For those inheriting property, the scenario shifts.

(The tax has been deferred, not eliminated.)Some people have been know to avoid this by...Dying while still owning the last property (capital gains and depreciation recapture go away.)Moving in to the last property as their primary AFTER it no longer functions as a rental.

I'm not that professional but I think a whole house filter would filter particulates like dirt but not chlorine. for chlorine you might need a reverse osmosis system for a specific drinking water tap to eliminate the taste as it's not practical or efficient to put an RO on the whole house supply. if skin issues from bathing are a problem you might need a softener. sometimes when kids have eczema doctors actually prescribe "bleach baths" where a small amount of chlorine bleach is added to the bath water. also many of the water treatment systems can be rented so maybe just rent it while they are there. regardless, proceed with data. water test, pediatrician diagnosis (if it's legal to ask for, no clue), and a system that is right for the application. sounds like the tenant is willing to help out which is awesome.

When he dies then his children get the properties tax free - the tax is eliminated!
